摘要
支架术和经皮腔内冠状动脉成形术联合应用对于直径≥3mm的病变血管可产生较为理想的再狭窄率和主要心血管事件发生率,然而对于直径< 3mm的病变血管而言,愈后不佳,因此现在小血管病变的介入治疗已成为关注的焦点。近年来除了传统的支架术外,还运用了各种新方法来治疗小血管病变,如药物涂层支架、洗脱支架、合理化支架、点支架、切割球囊成形术等。本文对上述各种方法的疗效作一综述。
The combined applications of stenting and percutaneous transluminal coronary angioplasty(PTCA)have facilitated large gains in the treatment of stenoses in vessels that are ≥3mm in diameter,decreasing the rates of restenosis and major adverse clinical events(MACE).However,for small coronary arteries(diameter<3mm)the result remains poor.So interventions for small coronary arteries have been attracting much concern nowadays.Recent years,besides conventional stenting,many other novel approaches,such as drug-coated stent,drug-eluting stent,provisional stenting,spot stenting and cutting balloon angioplasty,have been used for the therapy of small coronary arteries.This is a review about the novel interventional approaches and their therapeutic effects.
